An apparatus (10) is provided for producing continuous glass filaments (30). The apparatus (10) comprises a bushing (20) for supplying streams of molten glass and a drawing device (40) adapted to draw the streams into continuous glass filaments (30). A cooling device (50) is also provided and is located adjacent to the bushing (20) for drawing in heated air from a filament forming area beneath the bushing such that heat is convectively transferred away from the filament forming area.

L'invention concerne un appareil (10) pour la production de filaments de verre continus (30). Ledit appareil (10) comporte une filière (20) pour envoyer des flux de verre en fusion et un dispositif d'étirage (40) conçu pour étirer les flux et former des filaments de verre continus (30). Un dispositif de refroidissement (50) adjacent à la filière (20) pour aspirer l'air chauffé de la zone de formation des filaments, au-dessous de la filière, de sorte que la chaleur soit éloignée par convection de la zone de formation des filaments.
